利用扫描加记数程序实现百进制,适合VHDL的初学者使用.-increase in the use of scanning program in mind several hundred 229 and is suitable for beginners to use VHDL.

嵌入式系统的乘法器试验报告 包括源代码 用VHDl语言编写-Embedded System multiplier test report including source code language used VHDl

stm32与fpga之间的通信，协议是SPI的，可双向通信（双向通信需要自己例化，只例化了fpga到stm32）(Communication between STM32 and FPGA, the protocol is SPI, two-way communication (two-way communication needs to be taken as an example, only FPGA to STM32))

基于FPGA器件的DDS设计实现中的一个核心部分就是波形存储表的设计。首先采用LPM_ROM和 VHDL选择语句这两种方法进行波形存储表的设计和比较分析 然后考虑到硬件资源的有限性及DDS的精度要 求,对这两种方法的程序进行了优化 最后对这两种方法设计的程序进行仿真和硬件调试。结果表明:采用这两种 方法都能有效地实现DDS中波形存储表的设计。 (DDS-based FPGA devices designed to achieve one of the core of the waveform is stored in table design. First of all, choose to adopt LPM_ROM and VHDL statements of these two methods for the design waveform storage tables and comparative analysis and then, taking into account the limited hardware resources and the accuracy of DDS, the two methods to optimize the process the last of these two methods of process design simulation and hardware debugging. The results showed that: the use of these two methods are all effective ways to achieve the DDS waveform stored in the table design.)

vhdl对dds的原理设计，由衷要得论文价值。不后悔-right dds VHDL design principle, we sincerely value of fine papers. No regrets

实现了UART的底层协议，加入了控制器，其波特率可以根据使用进行调整；发送模块、接收模块相互独立，互不影响。(Realization of the underlying protocol UART, joined the controller baud rate can be adjusted according to use transmission module, receiver module are independent of each other.)

说明：  FPGA控制AD7321的模块，是本人亲自试验过的。有Verilog源码，和简单文档。(FPGA control module of the AD7321 is personally tested. There Verilog source code, and simple document.)
